Description

Technical Field

[0002] With the continuous development of social economy and the increasing improvement of scientific and technological levels, my country's chemical industry is also booming. Static crystallizer, as a device used for crystallization, can precipitate a crystal layer on the cooling wall of the crystallization plate through a static molten mixture, thereby achieving step-by-step crystallization and ultimately purifying one or more products in the mixture. It plays an important role in the chemical industry.

A stirring mechanism is also provided on the shell, and the stirring mechanism includes a stirring frame and a rotating motor. The stirring frame is located in the shell and is rotatably connected to the shell. The rotating motor is used to drive the stirring frame to rotate, so as to stir the material in the shell after the crystallization is completed. When in use, the cooling liner cools the material in the shell by heat transfer, so that the material gradually crystallizes. After the crystallization is completed, the stirring frame is driven by the rotating motor to stir the material in the shell, so that the material is stirred evenly.

[0004] Regarding the above-mentioned related technologies, since the crystal particles after static crystallization are large and distributed in the material, when the rotating motor just starts to drive the stirring frame, the stirring frame will encounter greater resistance, causing the load of the rotating motor to be too large, which reduces the service life of the stirring frame and the rotating motor, so it needs to be improved.

[0044] Reference Figure 3 and Figure 4 The stirring mechanism 3 further includes a bottom stirring assembly 35 and a linkage assembly 36. The bottom stirring assembly 35 includes a bottom shaft 351 and a bottom stirring frame 352. The bottom shaft 351 is vertically arranged, and the bottom end is fixedly connected to the inner bottom wall of the device body 1. The bottom stirring frame 352 is located at the bottom of the inner chamber of the device body 1, and is sleeved on the bottom shaft 351, and is rotatably connected to the bottom shaft 351 through a bearing.

[0045] Reference Figure 2 , Figure 3 and Figure 4 The outer side of the bottom stirring frame 352 is located at the lower side of the input pipe 21 and the output pipe 23 to stir the bottom of the equipment body 1. The top of the bottom stirring frame 352 is a vertical hollow tube, and two linkage grooves 3521 are also penetrated on the side wall of the top of the bottom stirring frame 352, and each linkage groove 3521 is spirally arranged along the axial direction of the linkage frame 361.

[0046] Reference Figure 3 and Figure 4 A linkage protrusion 3511 is also provided on the top side wall of the bottom shaft 351, and the linkage protrusion 3511 is integrally formed with the bottom shaft 351. The linkage assembly 36 includes a linkage frame 361, a driving rod 362 and a reset spring 363. A through groove matching the linkage protrusion 3511 is provided on the linkage frame 361, so that the linkage frame 361 can be sleeved on the top of the bottom shaft 351 and slidably connected with the bottom shaft 351. The linkage frame 361 is located on the displacement path of the bottom end of the spiral stirring blade 33.

[0047] Reference Figure 3 and Figure 4 In the embodiment of the present application, the number of the driving rods 362 is set to two, and the two driving rods 362 are respectively located on opposite sides of the linkage frame 361, and one end of each driving rod 362 is fixedly connected to the linkage frame 361.

[0048] Reference Figure 3 and Figure 4 The return spring 363 is located below the linkage frame 361 and is sleeved on the bottom shaft 351. The top of the return spring 363 abuts against the bottom of the linkage frame 361, and the bottom of the return spring abuts against the inner bottom wall of the bottom stirring frame 352, so that the linkage frame 361 is restored to the initial position through elastic force, thereby indirectly restoring the bottom stirring frame 352 to the initial position.

[0049] Reference Figure 2 , Figure 3 and Figure 4 In the initial state, the spiral stirring blade 33 is located above the crystallized material and does not contact the material. At this time, the bottom stirring frame 352 is located in the material and does not rotate. When the rotating member 343 drives the rotating shaft 341 to rotate, so that the rotating shaft 341 drives each rotating frame 321 to rotate in a circle through the bevel gear set 342, the rotating shaft 341 drives the moving frame 31 to slide back and forth in the vertical direction through the connecting frame 322.

[0050] Reference Figure 2 , Figure 3 and Figure 4 During this process, the moving frame 31 drives the buffer frame 41 to slide, so that the bottom of the spiral stirring blade 33 contacts the top of the crystallized material downward to loosen the material and stir the material during the loosening process. After the material is gradually loosened, the bottom of the spiral stirring blade 33 contacts the linkage frame 361, thereby pushing the linkage frame 361 to slide downward. During this process, the driving rod 362 moves downward accordingly, so that the driving rod 362 abuts against the inner wall of the linkage groove 3521, driving the bottom stirring frame 352 to rotate, so that the bottom stirring frame 352 stirs the crystallized material at the bottom of the equipment body 1.

Each outlet pipe 5 is also provided with an outlet valve 6 to control the opening and closing of the outlet pipe 5.

[0052] The implementation principle of a static crystallizer crystallization device in an embodiment of the present application is: when the rotating member 343 drives the rotating shaft 341 to rotate, so that the rotating shaft 341 drives each rotating frame 321 to rotate in a circle through the bevel gear set 342, the rotating shaft 341 drives the moving frame 31 to slide back and forth in the vertical direction through the connecting frame 322.

[0053] During this process, the moving frame 31 drives the buffer frame 41 to slide, so that the bottom of the spiral stirring blade 33 contacts the top of the crystallized material downward to loosen the material and stir the material during the loosening process. After the material is gradually loosened, the bottom of the spiral stirring blade 33 contacts the linkage frame 361, thereby pushing the linkage frame 361 to slide downward. During this process, the driving rod 362 moves downward accordingly, so that the driving rod 362 abuts against the inner wall of the linkage groove 3521, driving the bottom stirring frame 352 to rotate, so that the bottom stirring frame 352 stirs the crystallized material at the bottom of the equipment body 1.
